Corydalis flexuosa
'Porcelain Blue'

Robins-egg blue flowers with a Narcissus-esque scent and lacy foliage are the calling cards of this surprisingly hardy Corydalis. Finely divided bright green foliage forms a 12” high and 18” wide clump from which arise multiple airy flower spikes topped by over a dozen 1” true-blue flowers that look for all the world like little seahorses bobbing in the ocean. Loved by bees and hummers, the lightly fragrant flowers will appear in Spring and then re-bloom prolifically in the Fall. Unlike other Corydalis, this variety doesn’t go Summer dormant. It will want relief from midday heat so part shade or filtered sun will make it happy. Plant in fertile, moist but well-drained, neutral to lightly acidic soil and apply mulch to the Winter clump. May stay evergreen in zones 9b and higher. Hardy down to 10 degrees F.
